SanDisk 256GB Extreme PRO CFexpress Card Type B - SDCFE-256G-GN4NN

I use a MAC Studio and have daisy chained two LaCie 2big Dock units. The first is an older unit which does not support the CFexpress card format; it has on its front a USB 3.1, Compact Flash and a SD card reader. It is used as a Time Machine for the Mac and has and continues to work perfectly. I recently purchased a new Nikon camera, which uses the CFexpress card and an updated LaCie 2big Dock unit and daisy chained it to the Time Machine. The updated 2big Dock has card readers on its front, same as its predecessor, and supports the newer USB 3.2, CFast 2.0, CFExpress and the SD card. Open System Settings by clicking the Apple logo in the upper left hand part of your screen, then click About this MAC and finally More Info... You will be taken to System Settings, General, About. Now click System Report at the bottom of the dialogue box, under Hardware, click Thunderbolt/USB4 and at the top of the resulting screen expand the TB tree by dragging on the bottom of the dialogue box to reveal Thunderbolt/USB4 Bus 3; note that the MAC OS see's the device as an SSD Hard drive and not a removable drive. This means that inserting the CFexpress card into the reader does nothing. The card is not recognized within Disk Utility or in Finder and therefore the user is unable to import images captured to the CFexpress card using the newly acquired LaCie. I have only explored one option thus far, which is to connect the camera, with the CFexpress card inserted, via USB C cable directly to the MAC Studio. The camera is recognized and an import of the images proceeds, ...slowly, I might add. I am not knowledgeable enough to determine exactly where the problem lies. Is it something within the LaCie firmware that causes the MAC OS to recognize the bus as an SSD or is the MAC OS configured to not recognize third party CFexpress readers. Who knows? I spoke to Apple today, the Best Buy Camera dude and they both concur and advise to connect the camera directly to the MAC. Will research 3rd party readers tomorrow and update as necessary. Anybody have any further experience with this pls share. I am trying to declutter my work area as much as possible and the last thing I want is another dammed dongle.

Everything went as promised.....service was excellent

I have stored thousands of photos and videos on this camera storage device without any technical issues

I used this with my Nikon z7ii. This is a rock solid, dependable and fast transferring card. I have 2 I love it so much. Excellent value, go for it.

Good, fast and reliable

This is not difficult to use, even though some may say that it is. They are wrong. It is easy to use. They just don't know how it works and try to force it in backwards or upside down. This CFExpress card is sturdy compared to the SDHC cards and more reliable. It will store nearly 1000 raw images on my 45 megapixel camera. Most photographers only shoot a few hundred photos in a single session. If you need more than 1000 then you are probably doing something wrong

le doy solo 4 estrellas por q no estoy en contra de las nuevas herramientas, solo que es un problema tener tantos adaptadores y cables para poder hacer un respaldo en el ordenador, las camaras estaban bien con memorias SD, (pequeñas, comodas de llevar) con la marca no e tenido problemas ninguna me a fallado hasta ahora, por esa parte me siento muy seguro con la marca. Y seria un mejor servicio que tuvieran un adaptador de la marca con todas las entradas para las diferentes memorias y no tener que llenar el escritorio con tantas cosas, lo simple debe ser una prioridad.

Heres the catch the 128gb size has the write speed up to 1200MB/s and read speed up to 1700MB/s where as the 64gb write speed is 800MB/s and 1500MB/s so if you have a fast fps camera like D500 or D9 then you need the 128gb card
